General purpose motors with aluminum housing, protection up to IP66 and painting system up to C4 are suitable for a wide range of standard drive tasks in industrial environments and humid atmospheres. The design and architecture of the motors ensure maximum flexibility and minimum installation effort. Due to their particularly low weight, they are predestined for applications in pumps, fans and compressors.

Product overview

In addition to induction (asynchronous) motors for direct-on-line and converter operation, two different synchronous motor technologies are available. These need to be used always with a frequency converter (VSD).

Direct on line, converter capable motors

The proven induction motors from the Innomotics GP General Purpose Motors are optimized for line operation, and are available with efficiency classes up to IE4. All motors have the same power-shaft height assignment. As a consequence, there are no shaft height differences, making it easy to service or replace motors across all efficiency classes. These grid-optimized motors can also be operated with converters.

Converter-optimized motors

The variable-speed-drive motors are based on the platform of the Innomotics GP General Purpose Motors. The design corresponds to the line motors – the mechanical parts are identical. However, instead of the squirrel cage induction rotor, they utilize one of the two available synchronous technologies. Together with an appropriate frequency converter they provide an outstanding performance and reach an extremely high energy efficiency (IE4 or IE5), also at partial loads. In addition, a large number of the variations available for the line motors (types of construction, motor protection, terminal box position, and options) are also available for the VSD motors.

Synchronous reluctance motor
For particularly energy-efficient operation, with keeping the standard power-shaft height assignment, the best choice is a VSD system with an Innomotics reluctance motor. The reluctance technology, without any rotor winding, ensures particularly high dynamic performance and high efficiencies even in the partial load range, as well as high process quality.
Permanent magnet motor
This advanced technology with permanent magnets in the rotor enables not only an outstanding IE5 energy efficiency, but also a high power density. The permanent magnet motor can be even three frame sizes smaller than an induction motor of the same power rating. Furthermore these motors provide a constant torque from the lowest speed and cover high overloads and overspeeds.
